Gate



Patented June 1 1, 1940 UNITED STATES PATENT OFFICE 4' Claims. (01. 33-6) This invention relates to improvements in gates and has particular reference to a self-opening and closing gate, that is, a gate wherein a vehicle passing therethrough will both open and close the gate during the act of passing.

A further object is to provide means whereby a person may manually open and close the gate during transittherethrough.

A further object is to produce a device of this character which is simple inconstruction, economical to manufacture, and easy to install.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Fig, 1 is a-fragmentary top-plan view showing my gate installed; I Figure 2 is a longitudinal the gate taken on the line 2-2 of Figure 1.

Fig. 3 is a crosssectional view taken on the line 3-3 of Fig. 1;

Fig. 4 is a cross sectional view line4-4 ofFig.3; .1

Fig. 5 is a fragmentary cross sectional view showing the gate partly tipped; and

taken on the Fig. 6 is a cross sectional View showing one of through a large number of gates in passing from one section of land to another. Ofcourse, there is a great deal of delay experienced in opening and closing these gates. l

I have, therefore, devised an 'wherein a person may pass through the gates without stopping the vehicle in which he isriding, or if on factor horseback, he simply operates a lever conveniently arranged beside the road- Way, and the gate willsautomatically open.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the letter A represents a section of roadway adjacent the gate. In the present instance, I have shown this section as being formed of concrete,

used, such as posts placed in the ground.

On each side of the roadway I mount vertical 2 l on bothsides of the pivot bar It, which grooves are spaced-apart, corresponding to the spacing sectional view of I arrangement It is obvious, however, that any other supporting medium may be supports 5 which are braced as shown at 6. As

both supports carry the'same operating mechanism, but one will be described. The support consists of a plate 1 having an arcuate shaped cam 8. Pivotally securedto the-plate i above the cam 8 are two latch dogs 9 and H having their noses spaced apart a sufiicient distance to allow for the entry therebetween of the gate bar extension !2. Each of these dogs has a horizontally disposed lip, as shown at l3 and M respectively. At I 6 I have shown a horizontally disposed pivot bar, the top of which is fiushwith the roadway .surface. This pivot bar has its ends overhanging recesses l'l formed at the sides of the roadway and serves to pivotally support the gate side -plates I8, between which side plates the gate proper is secured, which gate is designated as a whole by the numeral l9.

= In the surface of the highway I provide grooves of the rails of the gate. Therefore, it is apparent that when the gate is swung downwardlyabout its pivots to either side of the pivot point, the rails, of the gate will lie Within the grooves so that the vehicle may pass thereover.

In orderto swing the gate intoits several positions, I provide an operating mechanism which comprises latch actuating sliders 22 (see Fig. 2) which are mounted parallel to the gate side plates l8 and have a hammer head cam 23 at their upper ends and cam slots 24 and 26 at their lower ends. The slot v2'1 permits vertical movement relative to the pivot bar I6, and the slot 28 permits vertical movement relative to the gate bar extension l2. By viewing Fig. 2 it will be noted that the hammer head cam 23 underlies the lips l3 and I4 of the dogs l9 and II. Gravity ordinarily holds the latch slider in the position of Fig. 2, but as asafety factor I provide a spring 29.]

In order to actuatethe latch mechanism from a remote point, it is necessary to provide push and pull rods upon each side of the highway and extending in opposite directions from the gate.

'As the action of these pull rods is identical, but- 34 serves as an actuating bar and, therefore, ex- I tends across the highway so as to be contacted by an approaching car travelling in either direction.

If it is desired to actuate the gate manually, I may provide a manual hand operated lever at each side of the gate, as illustrated in Fig. 6, where it will be noted that the pull rod 3| has a hand lever 38 pivoted adjacent thereto and a spring actuated tongue 39 which normally does not extend across the slot 4 I Extending through this slot l! is one end of a yoke pin carried by the yoke 34. Therefore, by pushing the tongue 39 across the slot and moving the lever against the pin, the yoke will be moved in the direction of the applied power,

For instance, if the parts are in the position of Fig. 6 and the lever is moved toward the left of the drawing, a pull upon the pin will merely swing the yoke and allow it to slide in the eye 33. If the parts, however, are in the dotted line position of this figure and movement of the lever is toward the right of the drawing, then the yoke pin will push against the rod 3i and perform the function of opening the gate away from the direction of the push.

The operation of my device is as follows:

Assuming that a vehicle approaches from the right of 3 and the wheels engage the yoke 3 movement will be transmitted through the pull rod ti on opposite sides of the roadway, and the ends of the pull rods will first ride up the cam slots 32 of the gate side plates it (see Fig. 2) and will cause the latch actuating slider 22 to move vertically, thus pushing the cam 23 against the lips i3 and E i and releasing the dogs. At the same time, the pull rods have moved above the axis of the pivot bar it, about which the gate is hinged; and, therefore, the gate as a whole, now being released from the dogs 9 and H, is free to move and will swing in the direction indicated in the full lines of Fig. 5, and the rails of the gate will be at a point below the level of the roadway, whereby the vehicle may pass thereover without injury to the gate.

When the vehicle reaches the opposite side of the gate and the wheels thereof impinge upon the next yoke, the result will be that the pull rods upon this side of the gate will now be moved toward the left of the drawing so that the far end of the eye will be in engagement with the yoke. Consequently, the vehicle passing over the yoke will transmit a pull to the pull rods. As a consequence, the gate will be swung to vertical position. This last-mentioned pull rod is shown in dotted lines in Fig. 5, it being understood that the pull is toward the left of the drawing. As the gate swings upwardly, the extension it will pass beneath one set of dogs and come to rest between both sets.

The manual operation of the gate is identical with that just described.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

In a gate of the character described, a shaft flush with the surface of the highway, a vertical standard on each side of the highway opposite the ends of the shaft, a gate above said shaft, vertically movable plates carried by the ends of the gate and pivotally mounted on the shaft, studs carried by the ends of the gate, latches carried by the standards and engaging the studs and normally holding the gate in a vertical position, remote means operated by a vehicle for moving said plates vertically for releasing the latch, and oscillating them on the shaft for swinging the gate down parallel with the highway.
